Revealing and characterization of circulating tumor cells (CTCs) is one of the most actively investigated field of oncology. It was established by the past time studies that some of these cells were in condition of apoptosis and so couldn’t initiate formation of a clinically significant metastasis. The novel opportunities associated with development of computer technologies and interferential microscopes facilitate the solution of many medico-biological problems. One of them is a method of determination of CTCs functional condition based on the phase-interferential characteristics of their nuclear structures which reflect cellular metabolic and proliferative activity and are the markers of their malignant transformation.
The analysis was carried out of the morphodensitometric biomarkers of the metastatic activity of circulating tumorous cells including conformational alterations of their nuclear structures. The reference collection of phase images of metastatic cells was created as well as the data of the morphodensitometric parameters of their metabolic activity was received.
A new information was received about heterogeneity of the circulating tumorous cells with different metastatic activity which allows the broadening of fundamental scientific knowledge concerning cancerogenesis, individualization of the observation and treatment of patients, improvement of the quality of treatment, and optimization of its cost.
It is well known that platelets play a central role in hemostasis and thrombosis, they also mediate tumor cell growth, dissemination and angiogenesis. The purpose of the present experiment was to evaluate living platelet size, function and morphology simultaneously in unactivated and activated states using Phase-Interference Microscope “Cytoscan” (Moscow, Russia). We enrolled 30 healthy volunteers, who had no past history of aeteriosclerosis-related disorders, such as coronary heart disease, cerebrovascular disease, hypertention, diabetes or hyperlipidemia and 30 patients with oropharynx cancer. We observed the optic-geometrical parameters of each isolated living cell and the distribution of platelets by sizes have been analysed to detect the dynamics of cell population heterogeneity. Simultaneously we identified 4 platelet forms that have different morphological features and different parameters of size distribution. We noticed that morphological platelet types correlate with morphometric platelet parameters. The data of polymorphisms of platelet reactivity in tumor progression can be used to improve patient outcomes in the cancer prevention and treatment. Moreover morphometric and functional platelet parameters can serve criteria of the efficiency of the radio- and chemotherapy carried out. In conclusion the computer phase-interference microscope provides rapid and effective analysis of living platelet morphology and function at the same time. The use of the computer phase-interference microscope could be an easy and fast method to check the state of platelets in patients with changed platelet activation and to follow a possible pharmacological therapy to reduce this phenomenon.
